To all whom it may concern."

Be it known that l, ffonaon Frrrnnenn'r @anrna, a citizen of the llnited States, residin at Grafton, in the county of Walsh ll and tate of North Dalrota, have invented certain new and useful lmprovements in .Flnvelopes; and l do hereby declare the following to he a full, clear, and exact description of the invention, such as will enlll able others skilled in the art to which it appertains to malre and use the same.

"llhis invention relates to envelopes and the primary object of the invention is to,

I provide an improved envelope especially lll adapted for photographers use embodying a pair of independent poclrets whereby films may be positioned in one pocket and the prints positioned in the other poclret and held separated from each other.

an A further object of the invention is to provide an improved envelope including a pair of independent poclrets which can be reversed, so as to expose an addressed portion hearing the senders name and address.

lllll A still further object of the invention is to provide a return envelope for photographers use including a hody having a pair of independent poclrets, the envelope having an improved fastener arranged to to hold the envelope in its original and reversed position.

A still further object of the invention is to provide an improved envelope of the ahove character, which is durable and of all ficient in use, one that is simple and easy to manufacture, and one which can he placed upon the marlret at a reasonable cost.

With these and other objects in view the invention consists in the novel construction,

an arrangement and formation of par%, as

will he hereinafter more specifically descrihed, claimed and illustrated in the accompanying drawings, forming a part thereof in which:

all Fi are l. is a plan view of the improved enve ope,

Figure 2 is a similar view part in section showing the side walls in folded position and secured to the wings.

to Figure 3 is a front view of the improved envelope showing same in its folded position,

Figure A is a transverse section of the same taken on line l-A of Figure 3.

il Figure 5 is an elevation of the improved envelope when the same is in its reversed position.

Fi re 6 is a transverse section talren on the line fl-ti of Figure 5.

Referring to the drawings in detail wherein similar reference characters designate corresponding parts throughout the till the transverse edges thereof which are adapted to he folded over the inner faces of said walls. of the walls 2 and 3 have 'ormed there on inner walls 5 and 6, which are adapted to be folded over the front and rear walls 2 and 3.. lhe sealing wings 4t carry any suitable adhesive, whereby the walls 5 and fl may be secured thereto. As clearly shown in Figure 2 of the drawings the walls 5 and 6 when folded over upon the rear walls 2 and 3 form a pair of independent compartments 7 and 8 which are adapted to receive different lrinds of articles to be posted, such as photographic films and prints.

The wall 6 carries a sealing tongue 9, the purpose of which, will he hereinafter more fully described. After the inner walls 5 and 6 have been folded over the front and rear walls 2 and 8 and sealed in position, the walls 2 and 3 are folded in abut ting relation to each other and the free edges thereof are secured together by fasteners 10, which will he hereinafter more fully de scrihed. The fasteners 10 may he made of thin mendahle metal or heavy cardboard or the lilre and includes the eye ll carried by the outer longitudinal edge of the walls 2 and the sealing tongue ll carried by the outer longitudinal edge of the wall 3..

The eye l1 comprises a triangular hase 12, which is secured to the inner face of the walls 2 and central longitudinal edge thereof and when the eye is made of metal the corners of the triangularly shaped base may he bent inwardly and through the walls and bent hack upon the hody late. The walls 5 and 2 are provided at t eir meeting portions with a slot 14, through which protrudes The outer lon itudinal edges illll lllll lllll lllll llll the projecting portions 15 of the eye, which is formed on the base 12. This projecting portion is provided with the openin receivin the locking tongue 11' whi includes t e triangular shaped base 16 and the outwardl extending bendable ton e 17 which exten s through an openin ormed in the meeting portions of the wal s 3 and 6. As stated this locking. tongue may be either made of bendable metal or heavy cardboard or the like. When the same is made of metal the angles of the triangle base are bent inwardly and through the paper forming the envelope. When the device is in folded posit-ion the bendable tongue is inserted through the opening in the extended portion 15 of the eye to firmly hold the envelope in its folded position. One of the walls 2 and 3 is provided with a ruled portion for addresses of persons to whom the envelope is to be sent. The wall 6, as clearly shown in Figure 2 has the address of the sender printed or stamped thereon so that the envelope can be used as a return envelope when desired.

When the device is to be used as a return envelope the innerwalls 5 and 6 are bent over the front-and rear walls 2 and 3 as described before, and the blank is then bent in the reversed direction, to position the front and rear walls 2 and 3 on the inner side and in abutting relation with each other and to position the walls 5 and 6 on the outer side. To prevent the envelope from opening when in position, the tongue 17 of the fastener 10 is positioned through the eye 15 which holds the same in position. The sealing flap 9 is then inserted in the compartment 7 which holds the contents of the envelope in osition against displacement.

From the oregoing description it can be seen that an improved envelope is provided in which a pair of compartments are formed for independent articles, which is so constructed that the envelope can be reversed so as to form a return envelope.

In practice, I have found that the form of my invention illustrated in the accompanyin drawings and referred to in the above escription, as the preferred embodiment, is the most efiicient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily-vary, I desire to emphasize that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required without sacrificing any of the advantages of my invention as set forth.

What I claim as new is:

1. A mailing envelope having independent pockets flexibly connected together at their mouths for reversal to facilitate use both as an original and as a return packet by presenting different surfaces outermost to receive the original address and the return address, cooperating means on the pockets to selectivel secure the pockets in either of their positions, and one of the pockets having a closure flap to function in one of the positions to extend into the opposite pocket to thus close both pockets.

2. A mailin envelope having independent pockets flexibiy connected together at their mouths for reversal to facilitate use both as an original and as a return packet by presenting different surfaces outermost to receive the original address and the return address cooperating means on the pockets to selectively secure the pockets in either of their positions, one of the pockets having a closure flap to function in one of the ositions to extend into the op osite poc et to thus close both pockets, said parts being made from a single blank, and said means comprising interlocking members along the lower edges of the pockets.

In testimony whereof I afiix my signature in presence of two witnesses.
